Abstract

L'invention concerne un dispositif et un procédé de fabrication d'une feuille de verre individuelle bombée comprenant une ceinture de compression périphérique, comprenant son chauffage à sa température de bombage dans un four, son bombage, et son refroidissement général, caractérisé en ce qu'une zone de la feuille au moins partiellement à l'intérieur de ladite ceinture de compression périphérique, dite zone refroidie localement, subit, après le chauffage de la feuille, un refroidissement local plus rapide que le refroidissement général, alors que la feuille est à une température d'au moins 530°C. La découpe de la feuille sur la zone localement refroidie créé des bords présentant des contraintes de compression de bord.The invention relates to a device and a method for manufacturing an individual bent glass sheet comprising a peripheral compression belt, comprising its heating to its bending temperature in a furnace, its bending, and its general cooling, characterized in that 'a zone of the sheet at least partially inside said peripheral compression belt, called the locally cooled zone, undergoes, after the heating of the sheet, a local cooling faster than the general cooling, while the sheet is at a temperature of at least 530 ° C. Cutting the sheet over the locally cooled area creates edges with edge compressive stresses.
